My present invention relates to new and improved detachable covers for spare automobile tires. v

The primary object of the invention is to 5 provide a novel andimproved form of covering, which is designed, arranged and adapte ed for neatly enclosing and protecting extra y spare tires, such. as are carried for emergency use by'automobiles." It has for a further object the production `of seamless, onepiece, knitted spare tire covers which 'are waterproof' and remarkably smooth-fitting in yappearance because of their mechanical construction andtheir novel methodof man- It'has for a further object the production.

of spare tire covers which are readily applied or removed from operative position and which -atiall timespresent a most 'attractive appearance, du'e to the process by which manufactured. 1

With the y\ioregoing and other objects in View, the novelty -will be hereinafter particularly described and set forth in the appended cla1ms.

` In the accompanying drawings, 4whlch form part of this application for Letters Patent and whereon like numerals refer to corresponding parts in thev several views: 80. Figure 1 re resents in pers ective a tubular knitted bo y-blank, form in continuous lengths, preferably upon a circular lmitting machine.-l

Figure 4 is a view corresponding with the preceding Figure 3, except-that the stretched cover has here been treated'and coated with an exterior leatherizingand water-proofingcompound.

This accomplished, the cover in yprocess of' manufacture, Water-proofed, leatherized and suitably grained, is re oved from its work form 3Q Its one end 6- is then provided with slightly projecting metallic studs 8, and its opposite end with the Wellknown metallic snap sockets 9, which together serve to adv' justably and det'achably connect such ends when overlapped, as shown in the completed product represented by Figure 6 of the drawings.

When constructed substantially as shown and described, the completed cover has some range of circumferential adjustment to proy pro vide for tires of different diameters asA the result of its let-out and take-up feature in. thel ends 6 and 7 of the completed structure.

It is also true that a single cover will stretch in width sufficiently to accommodate tires of varying Widths 'within certain limits.

i Where a drum form of cover is desired this is readily produced by supplying' a sihiple disk of seamless material to be stitched or otherwise -secured to the inner periphery of cover Aat'one side of the structure like a drum head.

T e method.o hereinbefo're indicated. for ucing the present improved spare tire cover, is onl one vof several methods by which the article can be made, and applicant therefore desires it understood .that he is not restricted toY any particular method 'butf .fabric for maintaining lays claim to the cover as an article lofmanremaining inthis case, lref lgardless of the method byl which produced. Having thusdescribed my improved process and product, what I now claini and` desireto secure by Letters Patent is:

1. As an article of manufacture a seamless coverfor spare tires comprising a universally elastic, knitted foundation fabric stretched into substantial conformity with the exterior surface ofthe tire to be covered, and means for retaining the cover in fits stretched operative form.-

2. As an article of manufacture a--seamless fitted cover for. spare tires comprising" a universally elastic, knitted foundation fabric. smoothl stretched into substantial conformity with the exterior surface of the tire to be covered, and means for retaining the cover in its stretched operative form.

3. Ars an article of manufacture a seamless cover for spare tires comprising a uni- -ufacture as defined by the several claims versally elastic knitted foundation fabric stretched into substantial conformity with the exterior surface ofthe tire to be covered, and a fixing filler incorporated in said stretched form. l l

4. AsVA an article 'of manufacture a seam'- less cover for spare tires comprising a umversally elastic knitted foundationv fabric stretched into substantial' conformity with the exterior surface of the tire to be covered,

and a suitable water roof fixing filler in? corporated in said fa ric for maintaining same'in its stretched and unwrinkled form.

In testimon whereof I aiix lmy si ature.
